THE AUDITORY MODELING TOOLBOX
EXP_GEORGANTI2013
Figures from Georganti et al. (2013)
Usage:
exp_georganti2013(flag);
Description:
exp_georganti2013(flags) reproduces figures from Georganti et al. (2013).
The following flags can be specified;
| 'fig9' | distance estimation for a small room |
| 'fig10' | distance estimation for a large room |
The figures show the computed distance-dependent feature BSMD-STD (Binaural spectral-magnitude difference standard deviation) for audio signals measured at different/receiver distances.
The BSMD-STD may be derived from any dual-channel signal (binaural/stereo recordings).
The BSMD-STD is related to the standard deviation of the magnitude spectrum of room impulse response, which is known to depend on the source/receiver distance. See Georganti et al. (2013) for more information on applications.
